50 
APPENDIX G: MEMORANDUM OF AGREEMENT

Transbay Terminal / Caltrain Downtown Extension / Redevelopment Project EIS/EIR G-3 

1 Department will assist TJPA in planning the scope and content of the proposed interpretive 

2 exhibit. In addition, TJPA will also invite the Oakland Heritage Alliance, the San Francisco 

3 Architectural Heritage, the California State Railroad Museum, and the Western Railway Museum 

4 to participate. TJPA, while retaining responsibility for the development of the exhibit, will 

5 consider, jointly with Department, the participating invitees’ recommendations when finalizing the 

6 exhibit design. TJPA will produce, install, and maintain the exhibit. 

7 

8 TJPA will also consult with the City of Oakland about its interest in having a similar interpretive 

9 exhibit in the East Bay. If agreement is reached prior to completion of final design of the 

10 Terminal, TJPA will provide and deliver exhibit materials to a venue provided by the City of 

11 Oakland. 

12 

13 B. Salvage 

14 

15 TJPA, in consultation with Department, will identify elements of the existing Transbay Transit 

16 Terminal that are suitable for salvage and interpretive use in the exhibit in the new Terminal or in 

17 museums. Within two years of signing of this agreement, TJPA will offer these items to 

18 San Francisco Architectural Heritage, the California State Railroad Museum, Sacramento, the 

19 Western Railway Museum, the Oakland Museum, and any other interested parties. Acceptance of 

20 items by interested parties must be completed at least 90 days prior to demolition of the 

21 Transbay Transit Terminal. TJPA will remove the items selected in a manner that minimizes 

22 damage and will deliver them with legal title to the recipient. Items not accepted for salvage or 

23 interpretive use will receive no further consideration under this agreement. 

24 

25 C. Oakland Museum of California Exhibit 

26 

27 TJPA will consult with Department and the Oakland Museum about contributing to Department’s 

28 exhibit at the Oakland Museum relating to the history and engineering of the major historic state 

29 bridges of the San Francisco Bay Area. TJPA will propose contributions to such an exhibit that

32 models, oral histories, and salvaged components from the terminal. In addition, TJPA will assist 

33 the Museum by contributing to the cost of preparing and presenting the exhibit, interpretive 

34 video, as well as the costs of an exhibit catalog or related museum publication in conjunction 

35 with the exhibit, in a manner and to the extent agreed upon by TJPA, Department, and the 

36 Oakland Museum of California if consultation results in agreement between TJPA and Oakland 

37 Museum prior to demolition of the existing Transbay Transit Terminal. TJPA has established a 

38 maximum budget of $50,000.00 for the Oakland Museum of California exhibit and the 

39 interpretive video. 

40 

41 D. Documentation 

42 

43 Prior to the start of any work that would have an adverse effect on historic properties, TJPA will 

44 consult with the California SHPO, to ensure that the Transbay Transit Terminal has been 

45 adequately recorded by past efforts. Collectively, these past studies, which include Department’s 

46 past recordation of a series of remodeling and seismic retrofit projects that have occurred since 

47 1993, may adequately document the building, making Historic American Buildings Survey/Historic 

48 American Engineering Record (HABS/HAER) documentation unnecessary. In addition, TJPA, 

49 assisted by Department, will seek to obtain the original drawings of the Transbay Transit 

50 Terminal by the architect Timothy Pflueger. If the drawings cannot be copied and included in the 

51 documentation, then TJPA will consult with SHPO regarding recordation level and specifications 

52 for completing additional documentation. When the SHPO finds the documentation to be 

53 adequate, then TJPA will compile this documentation into a comprehensive record. All 
APPENDIX G: MEMORANDUM OF AGREEMENT 

G-4 Transbay Terminal / Caltrain Downtown Extension / Redevelopment Project EIS/EIR 

1 documentation will be submitted to SHPO and Department Headquarters Library with a 

2 xerographic copy to the Department District 4 Office. TJPA will contact the following repositories 

3 to inquire if they would like to receive a xerographic copy of the documentation: History Center 

4 at the San Francisco Public Library, San Francisco Architectural Heritage, the Oakland History 

5 Room of the Oakland Public Library, the Oakland Museum of California, and the Western Railway 

6 Museum. TJPA will ensure that these records are accepted by SHPO prior to demolition of the 

7 Transbay Transit Terminal. 

8 

9 E. Reevaluation of the Bay Bridge

1 Appendix A: Protective Measures: 

2 

3 Following are mitigation measures to be implemented to protect properties eligible for on in the National 

4 Register of Historic Places. The measures described would be implemented by a combination of 

5 construction contract specifications, drawings, and provisions, as well as public affairs programs. TJPA 

6 and JPB staff would be assigned to work directly with the public to provide project information and to 

7 resolve construction-related problems. The TJPA and JPB will work with community residents, elected 

8 officials, local businesses, and community organizations to tailor the mitigation program to best meet 

9 community needs. Contractors will be monitored to assure that mitigation measures are met. 

10 

11 I. Preconstruction Activities 

12 

13 • Undertake building data survey. A pre-construction structural survey would be completed to 

14 determine the integrity of existing buildings adjacent to and over the proposed extension. This 

15 survey would be used to finalize detailed construction techniques along the alignment and as the 

16 baseline for monitoring construction impacts during and following construction. During construction, 

17 the TJPA and JPB would monitor adjacent buildings for movement and, if movement is detected, 

18 take immediate action to control the movement. 

19 

20 • Complete detailed geotechnical investigation. During final design, additional sampling (drilling 

21 and core samples) and analyses of subsurface soil/rock conditions would be used to detail and 

22 finalize the excavation and its support system to be used in the retained cut, cut-and-cover and 

23 tunnel portions of the extension. Current data, including subsurface sampling conducted in 1995 and 

24 1996 for the 1997 Caltrain DEIS/DEIR have been used to identify the proposed construction 

25 techniques presented in the following sections, which form the basis for the impact analysis that 

26 follows in Section 5.21. 

27 

28 II. General Construction Measures 

29 

30 • Provide signage. The TJPA and JPB would work with establishments affected by construction 

31 activities. Appropriate signage would be developed and displayed to direct both pedestrian and 

32 vehicular traffic to businesses via alternate routes. 

33 

34 • Install level deck. Decking at the under-street cut-and-cover sections would be installed flush 

35 with the existing street or sidewalk levels. 

36 

37 • Provide for efficient sidewalk design and maintenance. Wherever feasible, sidewalks would 

38 be maintained at the existing width during construction. Where a sidewalk must be temporarily 

39 narrowed during construction (e.g., deck installation), it would be restored to its original width 

40 during the majority of construction period. In some places this may require placing the temporary 

41 sidewalk actually on the deck. Each sidewalk design should be of good quality and approved by the 

42 Resident Engineer prior to construction. Handicapped access would be maintained during 

43 construction where feasible. 

44 

45 III. Soils/Geology 

46 

47 • Underpin existing buildings, where deemed necessary, to protect existing structures 

48 from potential damage that could result from excessive ground movements during 

49 construction. The design of the tunneling and the excavation procedures (and construction 

50 sequence), and the design of the temporary support system will be developed with the objective of 

51 controlling ground deformations within small enough levels to avoid damage to adjacent structures.

1 Where the risk of damage to adjacent structures is too great, special measures may be implemented 

2 such as: (1) underpinning, (2) ground improvement, and/or (3) strengthening of existing structures 

3 to mitigate the risks. 

4 

5 The cut-and-cover alignment passes near settlement-sensitive structures in the vicinity of the 

6 intersection of Second and Townsend streets, including buildings in the Rincon Point / South Beach 

7 Historic Warehouse – Industrial District (i.e., 166-178, 180, , and 350-360 Townsend Street). 

8 

9 The tunnel alignment passes under a number of old and settlement-sensitive structures in the 

10 vicinity of the intersection of Second and Townsend streets, including buildings in the Rincon Point / 

11 South Beach Historic Warehouse – Industrial District (i.e., 130, 136, 144-146, 148-154, and 162-164 

12 “Townsend Street; 634, 640, 650, and 670-680 Second Street; and 301-321 Brannan Street). 

13 

14 Even though the tunnel will be excavated using the stacked drift method, and even though the 

15 tunnel will be excavated in the Franciscan Rock formation, the risk of potential adverse impacts of 

16 tunneling on the existing buildings must be assessed, because the rock cover over the tunnel is 

17 rather shallow. 

18 

19 As part of the initial studies performed in 1996, preliminary plans were developed to 

20 protect/strengthen existing structures to mitigate the risk of adverse impacts of tunneling on existing 

21 structures. Underpinning, if it is deemed necessary, is one of the options for mitigating adverse 

22 effects of tunneling on the existing buildings. Underpinning involves modification of the foundations 

23 of the building so that the superstructure loads can be transferred beyond the zone of influence of 

24 tunneling. Underpinning may include internal strengthening of the superstructure, bracing, 

25 reinforcing the existing foundations, or replacing the existing foundations with deep foundations that 

26 are embedded outside the zone of influence of tunneling. 

27 

28 Other alternatives, in lieu of underpinning, involve strengthening of the rock between the building 

29 and the crown of the tunnel. Grouting in combination with inclined pin piles can be used not only to 

30 strengthen the rock but to make the rock mass over the tunnel act as a rigid beam, which would 

31 allow construction of the tunnels with no adverse effects on the buildings that are supported on 

32 shallow foundations over the tunnel. 

33 

34 Preliminary plans for underpinning have been developed that allow cost estimates to be made for 

35 underpinning. During the detailed design phase of the Project, underpinning plans will be developed 

36 specific to each of the buildings that may require it. It is not necessary at this stage of the Project 

37 to develop detailed underpinning plans. 

38 

39 These issues will be addressed on a case by case basis, along the alignment, during the detailed 

40 design phase of the Project. The methodology that is proposed for the Caltrain Downtown 

41 Extension, i.e. to design the support system to control ground deformations within tolerances, and 

42 selectivity strengthen structures that may be too weak to resist even small deformations, was 

43 successfully used for the Muni Metro Turnback project, and should be effective for the Caltrain 

44 Downtown Extension Project as well. 

45 

46 • Assure proper design and construction of pile supported foundations for structures to control 

47 potential settlement of the surface. Stability of excavations resultant impacts on adjacent structures 

48 can be controlled within tolerable limits by proper design and implementation of the excavation 

49 shoring systems.

1 IV. Air Emissions 

2 

3 • Upon completion of the construction phase, buildings with visible signs of dirt and debris from the 

4 construction site shall be power washed and/or painted (given that permission is obtained from the 

5 property owner to gain access to and wash the property with no fee charged by the owner). 

6 

7 V. Vibration 

8 

9 • Limit or prohibit use of construction techniques that create high vibration levels. At a 

10 minimum, processes such as pile driving would be prohibited at distances less than 250 feet from 

11 residences. 

12 

13 • Restrict procedures that contractors can use in vibration sensitive areas. It is often 

14 possible to employ alternative techniques that create lower vibration levels. For example, 

15 unrestricted pile driving is one activity that has considerable potential for causing annoying vibration. 

16 Using the cast-in-drilled-hole piling method instead will eliminate most potential for vibration impact 

17 from the piling. 

18 

19 • Require vibration monitoring during vibration intensive activities. 

20 

21 • Restrict the hours of vibration intensive activities such as pile driving to weekdays during daytime 

22 hours. 

23 

24 • Investigate alternative construction methods and practices to reduce the impacts in coordination 

25 with the construction contractor if resident annoyance from vibration becomes a problem. 

26 

27 • Include specific limits, practices and monitoring and reporting procedures for the use of controlled 

28 detonation. Controlled detonation may be required during tunnel construction through rock for both 

29 the cut-and-cover and stacked-drift construction methods, subject to additional geotechnical 

30 investigations and other considerations that would be determined during the final design and 

31 construction phases of the project. Any use of controlled detonation would be closely controlled and 

32 monitored to avoid damage to existing structures. Specific limits, practices, and monitoring and 

33 reporting procedures would be included within the contract documents to ensure that such 

34 construction methods, if used, would not exceed safety criteria. 

35 

36 • Use high-resilience track fasteners or a resiliently supported tie system for the Caltrain 

37 downtown extension for areas projected to exceed vibration criteria.
